Description

refrigerator {Refrigerator}

The present invention relates to a refrigerator for leaking a leakage current of a door to the outside.

BACKGROUND ART In general, a refrigerator is a device that maintains an internal temperature lower than an indoor temperature so that food can be stored in a refrigerated or frozen state for a long time.

In addition, when the refrigerator is sealed from the outside by a door and is operated by applying commercial power to the refrigerator, the storage chambers such as the refrigerating chamber and the freezing chamber are created in a low-temperature environment, so that the storage chamber temperature is usually lower than the outdoor temperature.

This is because the cold temperature in the refrigerator storage room and the hot temperature outside the refrigerator cause heat transfer through the edge material of the refrigerator door and form the dew point temperature. In particular, when the outside air is hot and humid, a large amount of dew may form on the edge of the refrigerator door.

As described above, when the temperature of the storage compartment of the refrigerator is lower than the outside temperature, dew may form on the boundary between the storage compartment and the outside air due to the temperature difference, in particular, on the edge of the refrigerator door. This not only deteriorates the image of the product, but it is also not good for hygiene, and the dew can flow down to the floor and pollute the area around the floor.

Therefore, it is necessary to prevent dew from forming on the boundary of the refrigerator, particularly on the edge of the refrigerator door.

To this end, in the related art, a condensing pipe is inserted into the body in contact with the door of the refrigerator, and the temperature of the door contacting surface is increased by the amount of heat dissipating heat from the condensing pipe, so that dew does not form on the body.

In this case, since a separate pipe is required to extend the condensing pipe to the door side, there is a problem in that the manufacturing cost is increased.

In one aspect, there is provided a refrigerator including a heat generating unit including a conductive member, a heat generating member, and an adhesive member, and a leakage current transmitting unit connecting the heat generating unit and the main body to transmit current leaked from the heat generating unit to the main body.

The main body further includes a fastening hole to which the fastening member is fastened, and an earth wire, and the leakage current transmitting unit is drawn out from the inside of the door to be electrically connected to the fastening member and the earth wire.

The door includes a housing having an accommodating space, and a power line for supplying power to the heat generating unit and a lead-out hole through which the leakage current transmitting unit is drawn are formed in the housing.

The heat generating unit includes a heat generating member that generates heat by receiving power, a conductive member that conducts heat generated from the heat generating member and is connected to a leakage current transmitting unit, and an adhesive member that attaches the heat generating member to the inside of the door.

The door includes a housing in which the heat insulating material is accommodated, and the adhesive member of the heat generating unit is attached to the heat insulating material in the housing.

The conductive member includes an aluminum foil.

According to one aspect, it is possible to prevent dew formation by using the heat generated from the heating unit.

In addition, by connecting the aluminum sheet, which is a conductive member of the heating part, to the body through a wire, the leakage current induced in the heating part is bypassed to the body, so that the leakage current does not affect the door, and electric shock accidents caused by leakage current can be reduced. have.

That is, by leaking the leakage current generated from the door during operation of the refrigerator to the outside, it is possible to prevent the detection of the leakage current generated when the user touches the door or the door handle.
